I met my bride to be a couple of months ago at Heathrow, and we have planned a wedding for February, her visa will run out in March. I know I will have to register the wedding, but I also understand that I will have to obtain a visa extension for two yearsm abd would like to ask a few questions?

When should i make the applicaiton to extend the visa?
Is it about £500, are there any other charges?
Will my wife be able to work or will that only be when she has UK residency, is it automatic after the two years or are there conditions?
Can we travel back to her home to visit her family and come back to the UK ok with the 2 year visa extension?

If anybody knows of anything else i should do at this point it would be really helpful?

Many Thanks

james
